JUSTUSHATTEMER, OF WEST NEW YORK, JERSEY, ASSIGNOR TO I-IARJJIVJIAN PECK COMPANYQOF NEl/V YORK, N. Y., A CORPORATION OF NEW YORK.'

To all whom it may concern Be it-known that LJUsT s Hartsnarnn, a citizen of the United States, residing at West New York, in the county of Hudson and Stateot' New Jersey, have invented certain; new and useful Improvements in Pedals; and I do hereby declare the following to be a full clear, and exact description ofthefiinv ention, such as will enable others skilled'inthe; art to which it appertains to make' andusethe same. y This invention relates to pedals for player 'grand'pianos and has for an object to providea pedal operably associated with a lyre of substantially the usual and ordinary form i provide guides associated with a lyre upon which a pedal structure slides vertically, with means for oounterbalancing the pedal both in raised andllowered positions.

-A further object of the invention is to provide improvedlneans for locking the pedal structure in lowered or operative posi tion. I

- A further object of the invention is to provide improved means for attaching'the pedal to thewind apparatus by means of a stirrup and flexible strap with means for tilting the stirrup in a predetermined direction when the pedal is, raised. r

A further object of the invention is to provide improved winding means for attaching cables controlling the pedals and counterweight.

Withthese and other objects in view the invention comprises certain novel constructions, combinations and arrangement of parts as will be hereinafter more" fully described and claimed.

In the drawings: Figure 1 is a view of the improvedpedal in side elevation shown in full lines in lowered or operative position and in dottedlinesat raised and an intermediate position. Fig. 2 is a view of the pedal structure and lyre in front elevation. Flg.

Patented Sept. 8, 1914.

Application filed April 13, 1913. Serial No. 762,044.

Fig. 5 1s a top plan view of the structure and operating means. Fig. 6 is a View of the pedal structure attached to a player grand piano. Fig. 7 is a sectional view through thewinding drum taken on line 7.7' of Fig. 5. Fig. 8 is an enlarged view in side elevation of the sliding block and lock. Fig. 9 is a sectional view oi the guiding block. Fig. 10 is a top plan view of the sliding block as invdicated by arrow 10 of Figs. '8 and 9. Fig.

11 is a detail view of the latch operating and lifting mechanism.

Like characters of reference designate corresponding parts throughout the. several views. I

, It it well known that in player pianos it is necessary to provide auxiliary pedals for operating the player mechanism and that it 'ous cabinet formation have been provided into which the pedals have been folded.

The present invention embodies a lyre 15 of substantially the usual and ordinary form,

the lyre illustrated in the drawings being shown conventionally it being understood that any ordinary form of lyre may be substituted therefor.

Along'the sides of the lyre guide rods 16 are erected secured to the base of the lyre by a cross bar 17 or its equivalent as shown at Fig. 3 of short bar members rigidly secured to the under side of said base. The tops of the rods are secured in any ap proved manner as by means of clips 17 shown at Figs. 1 and Slidable upon these guiderods 16 are blocks 18 carrying rigidly connected thereto arms 19 which together with the cross bar 20 rigidly carried thereby form the pedal supporting frlme. The blocks 18 are provided with rollers 21 as shown at Figs. 4, 9 and 10 which rollers are'grooved to embrace the guide'rods 16 and are journaled within the blocks 18.

To look the pedal supporting frame in lowered. position the blocks 18 are provided with latches 22 pivoted thereto as at 23 shown particularly at Fig. 8 and held yieldingly in position to engage the cross pieces 17 by springs 24. The latches are retracted by means of rods 25 pivoted to such latches and controlled by means of a lifting member 26 to which they are pivotally secured by means of the slot and keeper indicated at 27 especially in Fig. 11. It will, therefore, be apparent that when the end of the lifting member is lifted as indicated by the arrow at Figs. 1, 6 and 11 the said member will be moved upon its pivot 28 as shown at Fig. 11 to release the latches 22. Also to assist in suchlifting a counterweight 29 is provided slidable upon guide rods 30 which terminate and are secured at their lower ends in a cavity, recess or box 31 formed in the rear of the base of the 2 lyre, the recess and its addition to contain the same being sucwn at Figs. 1, 4 and 6. The counterweight is supported by a cable 32 passed over a pulley and about a winding drum 34, The winding drum as 25 will be seen more particularly from Figs. 2 and 7 is provided with three grooves, the lower one of which 34: accommodates the cable 32 and the others 35 and 36 accommodate respectively cables Q7 and 38 which 30 are connected with the arms of the sliding blocks 18, as shown particularly at Figs. 1 and 6. The cables 37 and 38 pass respectively over pulleys 39 and 40 by which the direction is changed to wind about the 3 5 drum 34:.

It will, therefore, be seen that the counterweight 29 sliding upon its rods 30 serves to counterbalance the pedal supporting structure. The pedal supporting structure car- 40 ries mounted thereon pedals 11 and 42 pivoted in any approved manner at the heel end as by pivots 43 whereby the pedals may be actuated by the foot of the user in substantially the usual and ordinary manner. 5 The pedals are provided with stirrups 44; to which straps 15 are connected extending upwardly to the wind apparatus to which it is connected in any suitable manner, not shown. Attached to the lower end of the 50 stra by any approved form of clamp or buckle 46 is a loop 46 which loosely embraces the bend of the stirrup. Secured beneath the pedal is a spring 47 whose free end passes the edge of the pedal and presses 55 forward behind the stirrup 4A. As seen in the first dotted position in Fig. 1, when the pedal begins to rise and tension on the strap is reduced, the stirrup is tilted as also indicated at that position to insure its lying 0 upon the pedal in proper relation shown in the upper dotted position of Fig. 1, the strap also folding down upon the top of the pedal when raised.

Oblique braces 18 are rigidly secured to 05 the cross bar 20 and to the arms 19 adjacent the blocks 18 which prevent any twisting action of the pedal support structure. A brace shown as a whole at 4 is also provided hinged to the lyre as indicated at 50 whereby it may be raised as seen in dot- 7 ted lines in Fig. 1 and held raised by a keeper 51. The latter may be a hook or catch of any suitable form, but in Fig. I have shown it as comprising two s rm jaws between which the brace is orce when raised.

The brace 49 is bifurcated at its lower end. and such extremities are provided with a5. stable points in the form of nuts 52 engaging sockets 53 as shown more particuiarly at Figs. 1 and 11. The brace 49 may lo moved upwardly or downwardly as in dicated in its two positions at Fig. 1 and *x'hcn down its'points rest in the bottom of the sockets to hold the pedal su port-e ing structure firmly in its downwar posi-w t the tension required being secured y Q. adpisting said points 52. \Vhen the is to be raised the brace -19 is first raisedf '.j; to the highest dotted line position in Figs: 1 and retained in such upward position by engaging said brace behind the kee or 51 whereupon the pedal structure is ree w rise as'an entirety as indicated by the two dotted positions in Fig. 1. Adjacent their, upper ends the guide rods 16 are provided; with rearwardly deflected portions 54 by: the use of which the pedal supportingf frame is raised from an inclined position as shown in full lines at Fig. 1 to a, horii 1m zontal position as shown in dotted lines in such figure whereby the pedals are obscured; under and behind the downwardly project ing flange 55 of the piano body. As shown at the various figures the regular piam 165 pedals 56, 57 and 58 are employed upon the lyre actuating respectively rods 59, 60 and, G1 which form no part of the present invention except as they work in harmonywith the auxiliary pedal structure disclosed 11 thereby.

I claim 1. The combination with a piano player, of-pedals slidable vertically relative there to, means to latch the pedals in lowered in position, and means whereby to manually lift the'pedals, said lifting means unlatch-f' ing the latching means. 4

2. The combination with a piano; of: guides disposed beneath the piano and vertical for the major portion of their length but having their upper portions deflecte to the rear, blocks 'slidable upon the guidu. and their deflected portions, and a pedal supporting structure carried by the block.

pedal supporting structure slidable upon some of said guides, a counter weight slidable upon other of said guides and cables connected to the supporting structure and the counterweight whereby the counterweight counterbalances the supporting structure.

5. The combinatlon with a piano, of

guides extending downwardly therefrom, a winding drum adjacent the tops of the guides, a pedal supporting structure slidable upon some of said guides, cables extending from said supporting structure to the drum, a counterweight slidable upon others of said guides, and a cable extending from the counterweight to said drum.

6. The combination with a piano embodying a body and means to support the body spaced above thefloor, of a lyre extending down from the body adjacent the floor; guides extending-vertically from the base of the lyre upwardly toward the body and bent at an angle where they join with the body; blocks slidable upon the guides and adapted to be changed from a Vertical to an inclination as they pass the bend oi the guides; and a pedal supporting structure carried by the blocks.

7. The combination with a piano em bodying a body and means to support the body spaced above the floor, of a lyre eX- tending down from the body; guides extending vertically from the base of the lyre upwardly and deflected to the rear where they join with the body; blocks slidable upon the guides and adapted to be changed from a Vertical to an inclination as they pass the bend of the uides, a pedal-sup porting structure carried by the blocks, other guides extending from said body straight downward, a counterweight slidable upon these guides, and a cable connecting said counterweight and blocks and passing intermediate its ends over a pulley.
